+# Utility script to stage Docker images in a public ECR repository so they can
+# referenced in Dockerfile's without depending on Docker Hub (and therefore
+# at risk of being rate limited and failing builds).
+
+# Prerequisites:
+# 1. Credentials for the Retail Demo Store staging AWS account where public
+#    images are staged.
+# 2. Your local AWS CLI environment configured with credentials to access
+#    the above mentioned account.
+# 3. AWS CLI 2.16+ (for ecr-public commands).
